It began around 12:30 p.m. when the alleged suspects stole items from the Salvatore Ferragamo store, a high-end retailer, located inside The Plaza at King of Prussia.
The suspects got into a car that fled at a high rate of speed. Police told Action News that they did not pursue the suspects.
The vehicle then crashed in the area of 651 S. Gulph Road after hitting an accountant's office and causing a gas leak.
"We heard a loud noise and I thought someone had a collision out front," said owner George Shoffner, who went on to say he tried to help the men after the crash.
"The police came up behind me and drew a gun and said to get away from the car, so we all backed off," he said.
Three of the suspects were seriously injured and were flown to local hospitals. Another was taken to the hospital by ambulance.
One suspect tried to flee on foot but was caught by a police dog on the scene.
Police say the suspects had dropped some of their stolen items in a parking lot at 555 Croton Road.
No one inside the accountant's office was hurt due, in part, because a new employee started on Wednesday.
"We had a new person starting today and we were getting ready to go out to lunch, so it was good she wasn't sitting there!" said Shoffner.
